These seemed like the best results through out the hundreds of different posts I've seen on this setup. It ended up giving me graphic artifacts and crashing my computer. When I rebooted it stayed this way, until I was able to get into my graphic card settings and reset them back to default.
Can someone please help me? What is the best config for Ultracoin on a R9 290X? I am going to be mining off two of them. How much hashing should I expect off each one? And what am I doing wrong?
I might suggest you use CG Watcher to manage your miner. I do. It keeps the miner active, by rebooting it if there is trouble at 2AM, as well as handling the fan speed changes and intensity changes if there is overheating.
